FIREPROOF CONSTRUCTION.

SPECIFCATION forming part of Letters Patent No. 555,084, dated February25, 1896.

Y Application filed December 5, 1895. Serial No. 571,123. (No model.)

To all whom it may concern:

Ee it known that I, ALEXANDER R. FOR- DYC-E, a citizen of the UnitedStates, residing at Newark, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in FireproofConstruction, of which the following is a full, clear, and exactdescription, such as will enable those skilled in the art to which it appertains to make and to use the same.

The invention relates to improvements in tireproof construction, andmore particularly to improvements in the framework or supports, wherebythe metallic lathing forming the skeleton or foundation for the iilling,forming walls, partitions, ceilings, te is held in. place.

It has for its object the provision of such a con struction whereby thelathin g can be easily and quickly secured in place, and whereby theentire skeleton or foundation will be firmly united and be able toresist to a considerable degree any force that may be applied to rupturethe same.

The invention is especially applicable to those constructions in whichthe lathing is formed of corrugated metallic plates.

The invention consists in the novel construction, combination andarrangement of parts, such as will be hereinafter fully described,pointed out in the appended claims, and illustrated in the accompanyingdrawings.

ln the accompanying drawings, in which similar letters of referencedesignate corresponding parts, Figure lis an elevation showing a sectionof a skeleton embodying the invention. Fig. 2 is a section on the line 22 of Fig. l. Fig. 3 is a section on the line 3 3 of Fig. l. Fig. et is asection on the line l et of Fig. l. Fig. 5 is a section on the line 5 5of Fig. l. Fig. G is a detail perspective view showing the two membersforming the corrugated beam detached. Fig. 7 is a similar view showing asection of the corrugated beam in which the beam proper and itscorrugated face are integral. Figs. 8 and 9 are detail views showing acorrugated reticulated metallic plate that is especially adapted to beused with the corrugated beam.

TVhile the invention is especially applicable to be used in aconstruction in which the lathin g is corrugated, and in whichapplication it will be described, it is obvious that other forms oflathin g may be used.

Referring to the drawings by letter, A designates a beam provided with acorrugated face a. The beam and the face may be cast integrally, asshown in Fig. 7, or they may be made of separatepieces of wrought-ironsuitably joined, as by rivets. (See Eig. 6.) The wrought-ironconstruction is the pre ferred form, however. The corrugations of theface a are provided with apertures a/ a in a line extending in thegeneral direction of the beam.

To the beam A, of which there may be any desired number as theconstruction may require, the lathing B is attached. The lathing in thisinstance is formed of corrugated wire fabric. The dimensions of thecorrugaticns are the same as those of the facing a, so that when thelatter and the fabric are brought together their respective convolutionswill register. After a sheet of lathing has been placed in position onthe beam it is secured in place by the locking rod or key C, which isforced through the openings a a in the facing a and the meshes of thelathing. In some instances it may be impractical to insert the key inthis manner. In such a case it can be placed against the lathing andsecured to the beam in any suitable manner and thereby secure the latterin place.

At intervals studs D D are placed. They are contained within theconvolutions of the lathing and are provided with apertures d d for thereception of the locking-rods C C.

G G are metallic tubes incorporated in the skeleton for the reception ofelectric wires, &c.

A modiiied form of the beam is designated by the letters E E. (See Figs.l and 4.) In this instance they are formed of corrugated plates and aregenerally used in pairs. Each is provided with apertures e e. They areplaced on opposite sides of the lathing and the three are secured by thelocking-rod e. The latter may be straight, as shown in Figs. 3 and 5, orit may be corrugated, as shown in Fig. El.

Figs. S and 9 show a lathing formed of corrug'ated reticulated metalplate, which is particularly adapted to be'used with the corrugatedbeams. The elongated openingsff, ex-

IOO

tending in opposite directions,are particularly suitable to allow thepassage of the locking or tie rod.

I-Iaying thus described my invention, what I claim, and desire to secureby Letters Patent, is-V l. In a fireproof construction, the combinationof the corrugated beam, the lathing mounted thereon, and the locking-rodsecuring the lathing to the beam, substantially as described. Y

2. In a reproof construction, the combination of the beam having acorrugated face, the lathing mounted on the said face, and thelocking-rod securing the lathing to the beam, substantially asdescribed.

In a fireproof construction, the combina-- tion of the corrugated beamhavin g perforations formed in the projections forming the corrugations,the lathing mounted on the said beam, and the locking-rod registeringwith the perforations in the beam and the meshes of the lathing,substantially as described.

e. In a ireproof construction, the combination of the corrugated beam,the lathing mounted thereon, and the corrugated lockingrod securing thebeam and lathing together, substantially as described.

5. In a reproof construction, the combination of the perforatedcorrugated beams, the latliing mounted between the same, and thelocking-rod interlacing with the said beams, through the perforations inthe latter, and the lathing, substantially as described.

G. In a fireproof construction, the combination of the perforatedcorrugated beams, the lathing mounted between the same, and thecorrugated locking-rod interlacing with the said beams and lathing,substantially as described.

7. A beam consisting of a main plain portion, and the corrugated stripfastened to the same to form a facing, substantially as described.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
